Innenring, Nadellager

All of theinternal rings have been heat treaded and fine machined. If the shaft cannolt be heat treated, it is better to use the internal ring as a sleeve. If the needle bearing and internal ring is used at the same time, the play is a common one and they are interchangeable. Our company also produces the inernal ring with accurate play and produces various internal rings with metric and British systems.
